Washington's diplomatic efforts in Sudan have inadvertently backfired, leaving the United States isolated and a ceasefire in the country's protracted conflict further out of reach. The strategy, aimed at pressuring the Sudanese Armed Forces (SAF) into an unconditional ceasefire, has instead created a diplomatic corner with few viable exit options for either the U.S. or the SAF.

For over three years, the U.S. has struggled to effectively respond to the devastating war in Sudan. The recent push for a ceasefire coincided with the 81st session of the United Nations General Assembly, where U.S. officials urged the SAF to halt hostilities and allow unimpeded humanitarian aid. This approach has been criticized for overlooking the dynamics of the conflict, particularly the role of the Rapid Support Forces (RSF) militia.

While the RSF has historically been quick to agree to deals that place it on equal footing with the national army, its commitment to peace is questionable given its actions. U.S. officials, however, have continued to refer to the RSF as the more "cooperative party" in diplomatic discussions. This perception has led Washington to focus its pressure campaign almost exclusively on the SAF, mistakenly believing that sufficient pressure would force the army to abandon its objectives.

The implications of this diplomatic misstep are significant. By alienating the SAF, the U.S. may have diminished its leverage in negotiating a lasting peace. The focus on sanctions, intended to cripple the SAF's military procurement, has historically proven ineffective against the Sudanese regime, which has shown resilience to long-term U.S. pressure.

Past U.S. administrations, including those of Presidents Donald Trump and Joe Biden, have imposed sanctions, but previous experiences with comprehensive sanctions over 20 years ago should have offered a cautionary tale. The recent imposition of sanctions on SAF military procurement networks in June, followed by chemical weapons sanctions in July without thorough investigation, further illustrates a potentially misguided approach. The subsequent U.S. initiative at the UN for a countrywide arms embargo, aimed at updating the outdated Darfur embargo, was widely seen as an unbalanced attempt to target the SAF's supply lines that had recently contributed to battlefield successes.

However, the UN Security Council initiative lacked sufficient support, facing the likely prospect of a Russian veto. The U.S. ultimately agreed to a one-month technical extension of the existing embargo, a move that suggests a compromise driven by a lack of consensus rather than strategic success.

This diplomatic strategy appears to have isolated Washington from key Sudanese actors and potentially emboldened the RSF. The focus on isolating the SAF through sanctions and embargoes, without a clear path for de-escalation or inclusive negotiations, risks prolonging the conflict and exacerbating the humanitarian crisis.

Unresolved questions remain regarding the U.S.'s future diplomatic strategy. Without a more balanced approach that engages all parties and acknowledges the complexities of the conflict, achieving a stable ceasefire and a peaceful resolution in Sudan appears increasingly distant.
